An Actual Shadow.

He said with glee, "Feel it rise and consume you. Feel the shadow of despair."

There is indeed a shadow on them. It was caused by the large palm falling on them. The palm blocked out the light as it fell lower and lower. It was an actual shadow that heralded their death. 

They would be crushed. But someone came to the rescue. It was that Supreme beast that saved them from his accumulated dragon breath. 

She has a dragon heart so she can still stand. She has a divine ability to devour attacks. She also has a large inner world created from the fusion of her dragon heart and a spatial divine ability to store all the attacks she has devoured. 

The only problems are that she has a limit and she can't absorb physical attacks. This attack is partly physical and partly magical which means she can absorb it. So she stood up against him now in defiance. 

Legion-5 roared at her, "Bend your knees beneath the shadow of despair. Submit to despair."
